This is typical rhetoric from someone without a very good understanding of basic....
...modern jet flying.

You are spot on BLCL.

What about :
02:06:50 (Bonin) Va pour les anti-ice. C'est toujours ça de pris.
Let's go for the anti-icing system. It's better than nothing.

Because they are flying through clouds, the pilots turn on the anti-icing system to try to keep ice off the flight surfaces; ice reduces the plane's aerodynamic efficiency, weighs it down, and in extreme cases, can cause it to crash.
If you read BEA's report, at 02:06:50 they noticed that SAT was -42°C, thence, anti-ice will NOT be needed.
"C'est toujours ça de pris" means they are satisfied not being forced to use anti-ice.
Pilots always begin with swiching nacelle anti-ice ON and then, if needed, they switch wing anti-ice ON.

Nacelle anti-ice were not switched ON until 02:10:03.
BEA does not mention wing anti-ice being switched ON at that time.


In the meantime Robert has been examining the radar system and has found that it has not been set up in the correct mode. Changing the settings.....
Once again, if you read BEA's report, "The copilot in the left seat moved the weather radar gain control to maximum, after noticing that he was in calibrated mode."
There is nothing "incorrect" using the radar in Calibrated mode.


Etc, etc.....
